ZYL-COVERED SEPAR-ABLE END 1911:3013},

Application filed August 22, 1924. Serial No. 733,526.

To all whom it may, concern;

Be it known that I, ELMER L. SCHU- MAOHER, a citizen ofsthe UnitedStates, residing at Southbridge, in the county of Worcester and StateofMassachusetts, have invented certain new and useful Improvements in.Zyl-Govered separable 'End Pieces, of which the following is aspecification.

.Heretofore it has been the customary practice to cover solid end piecesof spectacle frames, either by painting, dipping, or

otherwise applying a composition, prefers ably zyl or zylonite, hencethere is no claim made for the broad idea of a covering of thischaracter andthe manner by which the covering is applied.

However, a covering such as used on solid end pieces has been foundunsatisfactory for use in connection with divided or separable. endpieces, as such covering would encase both sections or members of theend piece and prevent access to the two 1116K}? bers thereof, when it isnecessary to make repairs. I v

In view of the above, and in connection with a divided .or separable endpiece, it is the purpose of the present invention to provideindividualcoverings forthe separable elements of the end piece, to permit theelements to be detached fromeach other to allow the rim to open orspring apart, either for'the repair of the lens or for the repair of theelements of the end piece, or the repair of the coverings.

Another purpose is the provision of recesses on opposite portions'of theadjacent faces of the elements of the end piece to receive marginalportions of the coverings to retain the latter in place.

Still another purpose is to provide a blank of fiber, preferably 'zylor-zylonite, which may be fitted to each of the elements of the endpiece,'suitahly heated and pressed in order to conform to the contour ofthe element of the end piece.

A further purpose is to provide a blank,

and made pliable, wherebythe composition may conform to the shape of theelement. The invention further aims to employ struck up tangs orprojections on the sides of each end piece element, in lieu of cavitiesor recesses, the fiber covering adaptedtobe heated, so that when thecovering takes the form of the end piece element it will also cooperatewith the tangsor projections and 7 thereby retain the covering inposition. i

It is to be understoodthat the particulars hereinglven are in no waylimited, and that still keeping within the scope of the invent10n, anydesired modifications of detail and desired proportions may be made inthe end plece construction and the coverings therefor according tocircumstances.

The invention comprises further features after set forth, shown in thedrawings, and claimed. y

Referring to the drawings, 1 designates a conventional spectacle frame,comprising the rims 2 and the nose bridge 3. The rims 2 may bezylcovered, as shown, and their remoteportions have separable ends -l-,which terminate in later: 1 end piece elements 5 and 6. The end pieceelements 5 and 6 are parallel and may be any shape or contour and anyproportions. Preferably the end piece elements extend laterally andrearwardly, and their adjacent faces in close position to theterminalso't the end pieces are provided with recesses or cut awayportions 7 and 8, which, when the end piece elements are securdtogether, receive the hinge ear 9 of a temple 10. i The hinge ear has acentral opening ll, through which a pivot pin 12 (which rises from thebottom of the recess or cut away portion 8 extends, thereby pivotallymounting the temple. This pivot pin 12 additionally serves to hold theend piece elements in register, due to the fact that it extends into andtits a cavity 153 constructed in the bottom of the recess or cut awayportion 7 of the end piece element 5.

The greater portion of each end piece element is provided with cavitiesor recesses 14, which arc substantially angular in contour, shownclearly in Figure 4 These recesses or cavities l-l are adjacent oppositeedges and the adjacent faces of the end piece elements.

The end piece elements are provided with coverings 1 5, which may beconstructed of any suitable libcr, preferably zyl or zylonite, and inapplying the covering it is first con structed in a blank, as disclosedin Figure .6. i This blanlt receives an imprint, such as shown at 16. ofthe shape of an end piece element, the blanlt beyond the margin oi theimprint having sufiicient material 17 to be bent and pressed up againstthe sides. of the end. piece element. To conform to the recessed or cutaway face of the end piece elen'ient, the additional material oi theblanlc, that is, beyond the imprint 16, cut away as at'lS. in applyingthe covering, which is in the term of a blank, as shown in Fi are (i,tlldllltlllk is subject to heat, su'llicient to render the blankpliable. Then the additional or excess material 17 is bent and pressedup against the sides of the end piece element, and the marginal portionsofthis additional material are pressed over and torccd into the recessesor cavities Ll, thereby retaining the covering in position. ,The xyl inits heated pliable condition readily conforms to the contour of the endpiece, regardless 031" its shape. Theend piece elc ments are tastenedtogether detach-ably by means of a screw 19, which is threaded throughthe adjacent end piece elements, as shown clearly in Figures 2, 3 and4;. The

head of the screw is countersunk in, the zyl, and the face oi. the head"is flush with the exterior of the zyl.

The blank in Figure 6 may be imprinted and stamped by any suitablemeans, preferably a suitable die,

Referring to Figure 7, 8 and 9, the covering. or blank is siniilarlyconstructed and applied, with the exception that the excess material ofthe blank, that is, beyond the imprint of the shape of the end pieceelement, is not disposed to overlie the inner face; of the end pieceelement. In order to secure the covering to the end piece element, shownin Figure. 8 and." 9, the sides of the ele ment are provided withrip-struck tangs or projections 20; The excess material, that is, beyondthe imprint of the end piece. element in the blank, when applying thecovering or blank to the construction of end piece element in Figures 7,8 and 9, is heated and pressed in close contact with the sides of theend piece element. The material cooperates with the tangs to secure thecovering-in, position. In this manner it is not necessary to recess theend piece elements, as in Figures 1 to 5 inclusive.

The invention having been set fortlnwhat is claimed is:

1. The combination with separable end piece elements provided withopposed recesses for the reception of a temple hinge ear, said elementshaving covering, receiving and attaching cavities, of compositioncoverings for said elements, engaged in the said receiving and attachingcavities, means for pivotally supporting the hinge ear of a temple insaid opposed recesses, and means for fastening said'end piece elementstogether.

2. In a device of the cliaracter described, an end piece comprising twometallic memlilli bers separable on a line of jpinder and, havingmarginal recesses adjoining the line of joinder and a non-metalliccovering over each metallic member having a, portion extending into andretained in the marginal recess with clearance for the metallic membersto, abut on the linev of joinder.

3. In a device o l the characten described, a. metallic end piece memberhaving a marginal, recess in one face and a nonsmetallic covering overthe other face and the edges of said metallic member extending into andretained in, the marginal recess. of the recessed face.

a. Inga device of; the character described, metallic end piece having arecessed portion and a non-metallic covering oven one face and edges ofsaid metallic end; piece extending into and retained: in the recessedportion of the. end piece.
